The construction of risk warning model of cognitive dysfunction in patients with vertigo after stroke
Objective To explore the influencing factors of cognitive dysfunction in patients with vertigo after stroke,and establish a risk warning model.Methods General clinical data of 205 patients with post-stroke vertigo admitted to the department of neurology and TCM the Brain Hospital affiliated to Nanjing Medical University from April 2021 to May 2024 were retrospectively analyzed and separated into cognitive dysfunction group(n=79)and normal cognitive function group(n=126)according to whether the patients had cognitive dysfunction.The general clinical data was compared,the risk factors affecting the cognitive function of patients with vertigo after stroke were analyzed,and the risk warning model was built based on the risk factors.ROC curve was used to investigate the predictive efficacy of the model in cognitive function of patients.Results There were significant differences between the two groups in place of residence,years of education,alcohol consumption,degree of vertigo,stroke frequency,focal site,and leukoaraiosis of patients(P＜0.05).Logistic regression analysis showed that drinking alcohol,hypertension,severe vertigo,lesion location in frontal lobe and leukoaraiosis were independent risk factors for cognitive dysfunction in vertigo patients after stroke(P＜0.05).The risk prediction model of cognitive dysfunction in post-stroke vertigo patients was constructed based on factors such as alcohol consumption,hypertension,vertigo degree,lesion location.ROC curve analysis of risk factors showed that the predictive sensitivity,specificity and AUC of these factors were based on alcohol consumption,hypertension,severe vertigo,frontal lobe location and leukoaraiosis can 85.34％,57.33％,and 0.782 in patients with post-stroke vertigo.Conclusions Warning models effectively assess the risk of cognitive impairment in vertigo patients after stroke.
